Representatives of the Denver school district and the teachers union met separately Tuesday with Gov. Jared Polis as the Democratic governor weighs whether to intervene in a pay dispute between the two sides.

A brief statement from Denver Public Schools described a “productive conversation” and said Polis “is continuing to push both sides to talk.” Denver Classroom Teachers Association officials also met with Polis and had no comment as they left, The Denver Post reported.

The meetings came at the request of state labor chief Joe Barela to “discuss the path forward” and to review an informal analysis by state budget officials of each side’s proposal.

Barela on Monday sent a sharply-worded letter to DPS and DCTA officials, criticizing the most recent teacher pay bargaining session last Thursday as “political theater.”

Union members and their supporters plan to gather Wednesday afternoon outside the Colorado State Capitol to deliver letters to Polis asking him not to intervene.

Polis has until Monday to decide whether to intervene, which could delay a Denver strike by as much as 180 days.

On Thursday, union leaders rejected the latest district offer, which called for investing $50 million more into teacher pay over the next three years. The offer represented movement by the district in the form of an additional $3 million for teacher pay in the 2020-21 school year, plus two additional years of cost-of-living raises.
